Application filed April 30. 1926: "serial" no. 105,767;

taching electrien'iotors to sewing machines.

It is one o'l he objects of the present invent-ion to provide a bracket attachment tor sewing inacl iines and like devices for yield ingly holding an electric in'o'tor'so that the pulley or drive wheel cit-gages the machine hand wheel.

1k further ob'ject of the invention is to provide-a motor bracket constructed so that the moto'rmay be manually pivoted away from the hand wheel,; the pivotal action being a n-st the tension of springwhereby LD g I v I when the device is released it wil automatically retarnto its wheel engaging position. A; further ob ect of the invention is to';' provide a motor carrying bracket oi the class described constructed so that when it is pivoted to disengage the pulley wheel from the hand wheel a pivotal dog member carried by the bracketpivoting handle will engage a'portion of the bracket to lock the motor in disengaged or tilted position, which position removes the pulley wheel from the hand wheel and permits the winding 01 bobbins.

A further object of the'invention is to provide a motor bracket of the class described which is easily attached to the head of a sewing machine of any type, is strong and durabletis efiicient in operatiom and is well adapted for the purposes described.

l Vith the above and other objects in View the invention consists of the improved'motor bracket, and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is an end view of a sewing machine head showing the bracket and motor in position; V

Fig. 2 is a side View thereof; and

Fig. 3 is a sectional View taken on line 33 of Fig. 2. p

Referring now more particularly to the drawing it will appear that the numeral 5. indicates the head portion of a sewing ma chine revolubly earying a hand wheel 6. A small motor 7 is provided forelectrically propelling said handwheel by means of the engagement between v the 'p'uLtey or drive wheel 80f the motor and the'hand wheel 6.

.The invention resides particularly in a bracket employed for supporting said motor to hold it in yielding engagement with the hand wheel. Said bracket comprises aplate Sattach'ed to the sid'e'o'tthc head-5by means of screws 10 and having. a pair oi 'spaced apart apertured. ears. 11 extending angular-- lyoutwardly therefrom. A pivot pin 12. extends through said cars and mounted thereon is a saddle shaped motor supporting member 13. As clearly shown, the motor I? is seated in the upper portion otthe sup-- porting member and 18 secured thereto. 15y

thisarrangementthe motor and supporting member aretree to pivot the rod 12 with respect toithehea'dbut any pivotal action away from the head is a ainst the tension exerted by a curved flat plate spring member let. Said spring plate is bent so as to engage the pivot rodf12 and its inner end is angular to fixedly engage under the plate 9, as at 16.

The pivot rod 12 is extended laterally and carries a sleeve 17. Clamped to said end portion of the rod, against the sleeve, by means of a threaded cap 18, is a lever arm 19, shaped as shown in Figs. 1 and 2. Said lever arm has an upper horizontal o'it-set portion 20, positioned between the head 5 and the inner'side of the motor. tov engage the motor. The free end of the lever arm is off-set horizontally in the opposite direction, as at 21, -to normally ride on the surfacev of the operating handle 22 pivoted to the machine head by means of a screw 23.

The operation of the bracket is such'that when the handle 22 is manually lifted, the lever arm 19 will be pivoted thereby to move the saddle and motor, as shown in dotted lines, against the tension of the spring memher, and wherein the pulley wheel disengages the hand wheel. In this position the motor may be locked by means of a pivotal dog 24 secured to the operating handle, as

atv 24, engaging a notch or shoulder 25 enlarged portion of the pivot screw 23. When the motor is thus disengaged, bobbins may be readily wound and when it is desired to return the motor to normal engaging position, it is merely necessary to pivot the dog to disengage the notch and the spring will return the parts to normal position.

From the foregoing description it will be seen that the improved motor bracket is of very simple and novel construction, and is well adapted for the purposes set'forth.

WV hat I claim as my invention is:

1. The combination with a sewing machine head having a hand wheel, of a motor bracket, comprising a bearing member secured to the side of the head, a saddle member pivotally carried by said bearing member, spring means engaging the saddle member for yieldingly holding it in a nor mal position, a handle member connected with said saddle member for pivoting it away from said head, and means for releasably locking the saddle member in pivoted position.

2. The combination with a sewing machine head having a hand wheel, of a motor bracket, comprising a bearing member secured to the side of the head, a saddle member pivotally carried by the bearing member, spring means engaging the saddle member for yieldingly holding it in a normal position, a lever member associated with said saddle member for pivoting it, and a handle pivoted to the head and engaging the lever member to move it.

3. The combination with a sewing machine head having a hand wheel, of a motor bracket, comprising a bearing member secured to the side of the head, a saddle mem ber pivotally carried by the bearing member,

spring means engaging the saddle member for yieldingly holding it in a normal position, a lever member associated with said saddle member for pivoting it, a handle, a pin pivotally connecting the handle to the head, said handle engaging the lever member to move it, a portion of said pivot pin being provided with a notch, and a dog member pivoted to the handle and engageable with said notch upon movement of the handle to releasably lock the device in pivoted position.

4:. In combinatioma sewing machine head having a hand wheel, a plate member secured to the side of the head and having a pair of projecting ears, a pivot rod extending through said ears, a saddle member mounted on said pivot rod, a motor carried by said saddle member, the pulley wheel of said motor normally being in engagement with said hand wheel, a plate spring member supported by said rod and engaging the plate member at one end and the saddle member at the other end portion, a lever member engaging the motor and secured to the pivot rod, a handle, a pin pivotally connecting the handle to the head, said handle engaging the lever member to move it, a portion of said pivot pin being provided with a notch, and a dog pivotally carriedby the handle, said dog being cngageable with said notch.

In testimony whereof, we affix our signatures.
